The quantum of the investment was not disclosed, but CSA said it aligned with its strategy to diversify and broaden its technical capabilities in mining.

SGC is a Perth-based group of geophysicists focused on the mining and petroleum sectors in Australia and overseas.

CSA managing director Jeff Elliott will join the SGC board as part of the agreement.

"I am very happy that our two companies are collaborating to pursue efficiencies and expansion,” he said.

“We have a common history and share very similar business cultures and values.

“SGC's reputation for geophysical consulting services is first class, and we look forward to working together and realising benefits from integrating our services."

SGC MD David Chapman said the partnership was an exciting development.

“Both companies are highly respected within Australia and internationally for their technical services and are now collaborating to bring a broader capability and greater value to projects at all stages; from exploration to extraction,” he said.
